7. Troubleshooting
If you encounter issues with your monitor, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/"No Signal" message | Incorrect input source selected, loose cable connection, insufficient power, source device not outputting signal. | Check all cable connections. Ensure the monitor is powered. Select the correct input source via the OSD menu. Verify your source device is configured to output to an external display. For USB-C, ensure the port supports DisplayPort Alt Mode. |
| Monitor does not power on | No power, faulty cable/adapter. | Ensure the power cable is securely connected to a working power source. Try a different USB-C port or power adapter if available. |
| Flickering or unstable display | Faulty cable, refresh rate mismatch, power fluctuations. | Try a different cable. Adjust the refresh rate in your device's display settings. Ensure stable power supply. |
| No sound from speakers/earphone jack | Volume too low, incorrect audio output selected on source device, faulty cable. | Increase monitor volume via OSD. Check audio output settings on your connected device. Ensure cables are fully inserted. |
| Image is too dark/bright/incorrect colors | OSD settings incorrect. | Adjust brightness, contrast, and color settings through the OSD menu. Reset OSD settings to factory defaults if necessary. |
